====== Intégration avec le Forum phpBB ======

Afin de clarifier ce que l'on trouve dans la page [[tips:integrate_with_phpbb|version "anglaise" de ce tips]] voici ce qui fonctionne :

Nommer le contenu du fichier ci-dessous phpbb.class.php puis mettez-le dans le répertoire inc/auth/

Modifiez si besoin la variable $location.'../phpBB2/'; par le nom du répertoire de votre forum.

Ensuite aller dans l'administration manager du DokuWiki, puis aller au niveau des configurations d'authentification, choisir phpbb.class.php, et choisissez ensuite le groupe par défaut du forum ex: user (pour les utilisateurs par défaut de l'ensemble du forum); puis choisissez le nom du superUtilisateur du DokuWiki parmi un des utilisateurs du forum.
